Red Bull Racing team boss Christian Horner believes Lewis Hamilton will be far from happy if he fails to win this year's Formula One world title.

Hamilton has two years remaining on his £10million-a-year contract with McLaren, and there is every indication a third trophyless season is in the offing.

Asked if he expected to be linked with Hamilton if McLaren fail to fulfil his expectations, Horner replied: 'Lewis is a great driver, a former world champion and one of the best there is.

'You would think he is not going to be happy if he has another barren year, but that's not to say we are looking for Lewis to come to our team.

'We're very happy with the two drivers we currently have, but it's more of a question you're going to need to ask Lewis than certainly I can answer for you.'

Hamilton announced a new partnership with one of the most powerful figures in global business, Simon Fuller on Monday.

'Lewis has chosen to go a different route' Horner added, after tieing reigning wolrd champion Sebastian Vettel to a new two-year contract.

'Obviously with the demands he has on himself, that is something that works for him,' added Horner. 'No two drivers are the same. It's whatever suits the individual best. With Sebastian it was very straightforward.

'For somebody so young, to be in control of his own destiny in the manner that he has been, is very refreshing.

'He doesn't have a big management group or organisation telling him what to do and when to do it. He makes his own decisions.'

Hamilton is clearly looking at his life beyond Formula One, in particular as he has previously aired tentative acting and musical ambitions.

Given Fuller's entertainment contacts, Hamilton is with the ideal representative for the day he decides he has had enough of F1.

'It was important I took my time to make this decision as it had to be right for my career and my long-term future,' said Hamilton.

'I spoke to many interested companies in recent months, but I felt Simon and his team not only wanted to help me become an even better racing driver, but they also shared my ambitions for the longer term.'
